I think the people who experienced the Apollo missions came away from that experience wondering to themselves, 'When can we get a chance to experience spaceflight?' I've heard that many, many times: that people got into a new career field hoping that they would be able to experience spaceflight.

I'm in favor of changing the destination of humans. There are a lot of manned missions that can be done, but not in the direction of the moon.

Space architectures capable of supporting a permanent human presence on Mars are extraordinarily complex, with many different interdependent systems.

It's time to open the space frontier to citizen explorers.

My sister called me "Buzzard" when I was a baby - she couldn't say "Brother" so I've been Buzz my whole life.

Globalisation means many other countries are asserting themselves and trying to take over leadership. Please don't ask Americans to let others assume the leadership of human exploration. We can do wonderful science on the Moon, and wonderful commercial things. Then we can pack up and move on to Mars.

The feeling of reduced gravity and the limitations of the space suit resulted in a slow-motion movement. Perhaps not too far from a trampoline, but without the springiness and instability.
